Parkinson's Disease Clinical Trial
Official title:
RQ-00000010 for Gastroparesis and Constipation in Parkinson's Disease
This is a study to determine the safety and tolerability of a new medicine (RQ10) for gastrointestinal symptoms in Parkinson's disease. The investigators will also begin to look at the effect of this medicine on gastrointestinal problems. The results will determine if future studies are appropriate. In this study, RQ10 will be compared to a placebo (a look-alike inactive substance). Participation will include multiple office visits. Approximately 48 people will participate.
This is a phase Ib study with the primary objectives of determining the safety and tolerability as well as pharmacokinetics after single ascending doses (SAD) and multiple ascending doses (MAD) of RQ10 in Parkinson's disease patients. A secondary objective will be to assess the impact of single doses of RQ10 on gastric emptying in Parkinson's Disease patients as well as the effects of RQ10 on gastroparesis symptoms. The expected results of this exploratory phase Ib study will allow deciding about whether to proceed with further development of RQ10 in Parkinson's Disease patients ("go-no go") and help design a formal phase IIa "proof of concept" study by informing repeat-dose selection and possible effect sizes in Parkinson's Disease patients. ;
